Kusintha kwina kwazinthu zopangira mapulasitiki

1. Kusiyanasiyana kwamakampani opanga mapulasitiki
Kutembenuza mbiri ya matumba apulasitiki, tidzapeza kuti mapulasitiki apulasitiki ali ndi mbiri ya zaka zoposa 100.Tsopano m'zaka za zana la 21, sayansi ndi ukadaulo zikupitilizabe kukula, zida zatsopano ndi matekinoloje atsopano akupitilizabe, polyethylene, pepala, zojambulazo za aluminiyamu, mapulasitiki osiyanasiyana, zida zophatikizika ndi zida zina zomangira zimagwiritsidwa ntchito kwambiri, ma CD a aseptic, ma CD shockproof, anti- ma static ma CD, anti-ana Packaging, kuphatikiza kuyika, kuyika kophatikiza, zopangira zamankhwala ndi matekinoloje ena akukula, ndipo mawonekedwe atsopano ndi zida monga matumba apulasitiki oyimilira atuluka, zomwe zalimbitsa ntchito zonyamula mu. njira zambiri.

2. Nkhani za chitetezo cha zipangizo zapulasitiki
M’mbuyomu, matumba apulasitiki oyikamo munali zinthu zopangira pulasitiki ndi bisphenol A (BPA), zomwe ndi zovulaza thanzi la munthu, ndipo nkhani zotere zimakonda kumveka.Chifukwa chake, malingaliro a anthu pakuyika mapulasitiki ndi "poizoni komanso osapatsa thanzi".Kuonjezera apo, amalonda ena osakhulupirika amagwiritsa ntchito zipangizo zomwe sizikugwirizana ndi zofunikira kuti achepetse ndalama, zomwe zimakulitsa chithunzithunzi choipa cha zipangizo zapulasitiki.Chifukwa cha zotsatira zoyipazi, anthu ali ndi gawo lina la kukana kuyika pulasitiki, koma kwenikweni, mapulasitiki omwe amagwiritsidwa ntchito poyika chakudya amakhala ndi malamulo a EU ndi mayiko, ndipo zida zomwe zimagwiritsidwa ntchito ndi mabizinesi ziyenera kukwaniritsa zofunikira za malamulowa. , kuphatikizapo pali malamulo okhwima a EU ndi malamulo a REACH atsatanetsatane pazinthu zapulasitiki zomwe zimakumana ndi chakudya.
Bungwe la British Plastics Federation BPF linanena kuti mapepala apulasitiki omwe alipo panopa si otetezeka okha, komanso amathandiza kwambiri pa thanzi la anthu komanso kupita patsogolo kwa anthu.

3. Ma biopolymer owonongeka amakhala njira yatsopano yopangira zida
Kutuluka kwa zinthu zowola kumapangitsa kuti zinthu zolongedza zikhale zatsopano.Kukhazikika kwazakudya, chitetezo komanso mtundu wazinthu zopangira zinthu za biopolymer zayesedwa mobwerezabwereza ndikutsimikiziridwa, zomwe zatsimikizira kuti matumba onyamula zinthu omwe amatha kuwonongeka ndi biodegradable ndiye ma CD abwino kwambiri padziko lonse lapansi.
Pakali pano, ma polima owonongeka akhoza kugawidwa m'magulu awiri: zachilengedwe ndi kupanga.Ma polima owonongeka achilengedwe akuphatikizapo wowuma, mapadi, ma polysaccharides, chitin, chitosan ndi zotumphukira zake, ndi zina zambiri;ma polima opangidwa owonongeka amagawidwa m'magulu awiri: kaphatikizidwe ka bakiteriya ndi yokumba.Ma polima owonongeka opangidwa ndi mabakiteriya akuphatikizapo poly Hydroxyalkyl alcohol esters (PHAs), poly(malate), ma polima owonongeka kuphatikiza polyhydroxyesters, polycaprolactone (PCL), polycyanoacrylate (PACA), etc.
Masiku ano, ndi kusintha kosalekeza kwa moyo wakuthupi, anthu amayang'anitsitsa kwambiri kuyika kwa zinthu, ndipo chitetezo ndi chitetezo cha chilengedwe cha ma CD zakhala zolinga zomveka bwino.Chifukwa chake, momwe mungayambitsire zobiriwira zobiriwira komanso zopanda zowononga zakhala mutu watsopano womwe makampani onyamula katundu m'dziko langa ayamba kuyang'ana.
